I don't remember if I posted this.

Louisiana is losing coastal marshlands at a rate of about a football field every 90 minutes - some 2000 sq miles since 1932, when reliable measurements begin. The causes are sea-level rise, subsidence due to oil extraction, lack of fresh mud due to river containment by levees, and worst of all, the indiscriminant cutting of canals, mostly for oil and gas extraction. Each new hurricane sends storm surge through the canals and into the remaining marshes, shredding them further and just "rolling 'em up like a rug," as one local told me.

I'm in New Orleans right now to participate in the exhibition "Our Insurgent Ecologies," which is a kind of continuation or fresh start of the Anthropocene River program organized with Berlin's HKW in 2019. You can see my mapping project, Hourglass River, at the link below, plus the exhibition program.

#Louisiana ’s newly released #draft of the state’s 2023 #CoastalMasterPlan proposes to spend $16 billion on construction new #TidalMarshes as a key #strategy to #combat #coastal #LandLoss.
A new study published in journal #Ecosphere & funded by the #NOAA RESTORE #Science Program addresses this issue, and the results provide #PositiveNews for the state’s plans to #rebuild the #coastline .
